Re: Build that 71 402 already

Interesting- now I’ve got to go look at mine. I thought Mn offered better corrosion protection but I may be mistaken. My trucks are living a gentle retirement so the oem Mn will do fine.

I looked into regalvanizing my oem fuel tank in the blazer. Apparently that’s akin to clear zinc somehow but results in larger crystals. Only mentioning because I wonder if crystal size can vary based on chemical milieu and/or temperature at time/place of plating.
